..I think the Subject probably says it all..

Since upgrading to 4.6, the Timer plasmoid / widget doesn't resize to fit on panel properly. It seems to have a fixed maximum width and height; in previous versions of kde4 it would re-size to match the height of the panel automatically (if the panel is made very thin it will shrink, but it won't get larger than its default <very small> size; it re-sizes fine on the desktop).

Anyone know how to fix this?

Thanks

This may be a deliberate decision in some parts, however given how the size is quite small it could pose an accessibility issue. I suggest filing a bug report at bugs.kde.org. (Note: I was able to reproduce on trunk)

Which widget is this? Did it come with KDE or did you install it from kde-apps.org?

I know this topic is a couple months old, but the OP is referring to the included Timer plasmoid.

This issue still occurs under Trunk.
